Vladimir Putin meets North Korea's Kim Jong-un at Russia's Vostochny Cosmodrome spaceport for 5-hour summit

Russian President Vladimir Putin met with North Korean leader Kim Jong Un at a spaceport on Wednesday (Sept. 13), likely discussing a range of possibilities for space-related cooperation.

The leaders of the internationally isolated countries met for a five-hour summit at Russia's Vostochny Cosmodrome, in the far east of the country.

The talks between the pair attracted global attention amid Russia's ongoing invasion of Ukraine and the possibility of deepened military cooperation between the two countries — particularly Moscow seeking to obtain artillery and ammunition to support its war effort.

The meeting and its setting highlighted that space exchanges were to be discussed between Russia and the Democratic People's Republic of Korea (DPRK). The leaders observed a new Soyuz-2 rocket launch facility from a viewing area during the visit, according to press reports.

The BBC noted that Putin told reporters that "the leader of the DPRK shows great interest in rocket engineering."

Rockets for launching satellites are similar in many ways to intercontinental ballistic missiles (ICBM) that can launch nuclear payloads. While launch vehicles insert satellites into particular orbits, ICBMs remain suborbital and release payloads that then fall to Earth on ballistic trajectories. North Korea — which, notably, has developed nuclear weapons and is looking to improve its delivery systems — is likely interested in both.

North Korea has failed with two attempts to launch spy satellites this year, and its last remaining — and already defunct — satellite is expected to reenter Earth's atmosphere within days. 

As well as improving its rocket technology, the reclusive state may also be seeking assistance for its satellite programs.

The AP reported that Thae Song, chairman of North Korea's space science and technology committee, was among the delegation in Russia, suggesting that possible Russian assistance for space systems such as spy satellites may have been discussed.

Imagery from space can provide information on adversaries' military-related activities and movements and inform planning and national defense strategies.

The summit also generated unconfirmed speculation that the pair could collaborate to send North Korean astronauts to space. 

Reporter and author Anatoly Zak, who runs RussianSpaceWeb.com, tweeted that a short-duration orbital joint crewed mission on a Russian Soyuz spacecraft was one speculative possibility. A more antagonistic approach would see Russia carry North Korean astronauts to the International Space Station (ISS). Such a proposal would be met by strong opposition by other ISS partners, particularly the United States.

Russia has lost a number of space cooperation partners and customers following its decision to invade Ukraine in February 2022. The country is currently training an astronaut from Belarus, another largely isolated, authoritarian nation, to travel to the ISS in March 2023.
